no noticeably gain in fuel mileage

People in reviews raving about this eco combo. I am on the verge of giving up the adjustment for the chip simply I couldn’t adapt this kit to my 500 SLC to extract some more MPG out of my engine having 300K miles on it. Although engine is pepped up and throttle response smoother out, other than that there is no noticeably gain in fuel mileage. For me this was money down the drain.

has brought my gas mileage back

I bought this fuel saving combo from this company and it works great. I installed a high flow (removed) exhaust with X-pipes and actually magnum kit has brought my gas mileage back to where was plus I have the extra horsepower. The only cons was the installation of this intake add-on. Chips installs hassle free.

unhappy with the level of skill

unhappy with the level of skill this kit assumes, the package came in mint condition in less than 4 days from the date of orderthey shipped it art no cost but openning up the parcel, there were no specific instructions. Neither video nor photos where to, how to put on the components. Even though technicians were more then willing to guide us thru the setup, i thought i purchased something that direct fits my M235. The only bonus is that seemingly fuel saving is attained and the kit works as advertized delivering the gains said on website.

the jury is still out

intake's pipe diameter was smaller than the original, but we were able to make it fit, though I say definite boost in horsepower. after 3 consecutive tanks results shows less mileage improvement than advertized. i did expect dramatic changes but so far fuel mileage seems to increase by 4 up to 6 MPG only. the jury is still out.

more power and saves gas

pretty cool jet air like a little intake turbo more power and saves gas i like it sounds pretty robust when mashing the gas and looks fine in engine bay it really works, the only downside is complex to install the intake but no doubt its worth the money

This thing is awesome!

My gosh! This thing is awesome! It helped my G1500 a lot. Not only does my car get an unbelievable 21 MPG, but its packed more than 17 extra horses under my hood. Absolutely incredible. Gas saver kit is great, also I'm delighted by their technical CS. I needed help with chip wiring. Bear in mind you have to be mechanically inclined otherwise go hire a mechanic working in a tuning shop.

This fuel saver kit is highly recommended

Right on the money. This fuel saver kit is highly recommended if you are eager to save, even though you have to invest a lot! Thanks for superfast follow ups, Jake, thanks for dedicating your full attention to my concern. Dyna boost install was a breeze but jet air does require intense skill, tooling and additional accessories were not included in the package. Thats the only kickback I can tell.

Maybe there needs to be a holistic mileage test

Maybe there needs to be a holistic mileage test before and after the installation of this "economizer combo" to see if there is any change at all. As I'm a city driver hard to tell if there is any improvement. Time will tell after we go north to thessaloniki with the wife and the kids.

immediately saw significant MPG gain

Placed this gas saver combo on my naturally aspirated engine and immediately saw significant MPG gain and I'm a bit leary of stating performance boost also is slightly moticeable. Car went down from 12 L/h to 10.4 at 100 km/h. 300 us dollars, I feel abit pricey! Asode from that this is a great deal.
